THE CLASSIFICATION OF GEACILAKIA AND ALLIED 



GENEKA. 



By T. A. Chapman, M.D., F.E.S. 



(Continued from p. 88.) 



I DO not propose to go into detail as to the habits of these 

 larvEe ; that would be to write a life-history of each species, 

 since, though there are some small groups of Gracilaria and 

 Lithocolletis in which one life-history might be written for all 

 the species, altering for each little more than the habitat and 

 food-plant, it is more widely the case that each species has 

 special habits of its own — in its form of mine, in its life out of 

 the mine, in its formation of a cocoon, and so on. There are, 

 nevertheless, things that may be glanced at, as they are probably 

 important as regards classification within the group. 



The group being by its pupal characters a high one amongst 

 the Incompletae, there is no doubt that it had amongst its not 

 very remote ancestors a form something like Buccidatrix in 

 living at first as a leaf-miner, afterwards as an external larva. 

 Bucculatrix may have been derived from the same ancestor, 

 retaining a more primitive pupa, but advancing in having a larva 

 in its later stages living externally and exposed. The primitive 

 Gracilarian must have had a mining larva in its early stages ; 

 an external but leaf-rolling larva in the later. It must then
